ZR40401R41

Overview

The ZR40401R41 is a precision micropower shunt voltage reference providing a nominal output of 4.1V with 1% initial accuracy. It utilizes a bandgap circuit design and operates within an industrial temperature range from -40°C to +85°C. The device features a typical temperature coefficient of 20ppm/°C and requires no external stabilizing capacitor for stability. Recommended operating current ranges from 60µA to 15mA, with absolute maximum ratings supporting up to 25mA reverse current and transient withstand capability up to 200mA.

Feature Summary

• Bandgap circuit design ensures stable voltage reference without requiring external capacitors
• Capable of reaching stable operating conditions in microseconds due to superior switching capability
• Robust construction allows the device to withstand transient effects and high currents

Applications

• Battery powered and portable equipment
• Metering and measurement systems
• Instrumentation and test equipment
• Data acquisition systems
• Precision power supplies and crystal oscillators

Procurement Notes

Verify the specific package suffix 'R' corresponds to the E-Line, 3-pin reversed configuration when sourcing this component. Confirm that the 1% tolerance designation matches the required accuracy for the application. Ensure the operating environment remains within the specified -40°C to +85°C industrial temperature range to maintain guaranteed performance specifications.

Selection Notes

Select this component for applications requiring a compact surface-mount or through-hole voltage reference with low quiescent current consumption. The absence of external stabilization components simplifies circuit design. Consider the 20ppm/°C temperature coefficient for thermal stability requirements and verify that the 15mA maximum operating current aligns with the load demands of the target system.
